Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

Location & Local Information
Possum Kingdom Lake, a reservoir in north-central Texas, experiences noticeable seasonal shifts in surface water temperature. In winter the lake commonly falls to roughly 40–55°F (4–13°C) near the surface, while spring sees a rise into the mid-50s to low 70s°F (13–22°C). Summer surface temperatures frequently reach the mid-70s to upper 80s°F (24–31°C), sometimes touching the low 90s°F (around 33°C) during heat waves, and autumn typically cools back into the 60s–70s°F (16–24°C) range. These figures vary with recent weather, wind, water depth and inflows; shallower coves warm more quickly and deeper sections remain cooler.
Swimming at Possum Kingdom Lake is permitted and is a common recreational activity, especially at park beaches and designated swim areas maintained for visitors. Because it is a managed reservoir used for boating and fishing as well as leisure, swimmers are expected to follow posted rules and warnings: watercraft traffic, submerged structures, sudden drop-offs and changing temperatures can create hazards. Cold winter or early spring water can pose a hypothermia risk, while summer sun and warm water increase activity but also require attention to hydration and safety. Checking current advisories and choosing marked swim zones helps ensure a safer experience.
